Answer:
Since, \[\text{average
velocity}=\frac{displacement}{total\,time\,taken}\]and \[\text{average speed
}=\frac{total\,dis\tan ce\,travelled}{total\,time\,taken}\].
Since, displacement
of an object can be equal to or less than the total distance travelled in a
given time, hence, average velocity of an object over an interval of time is
either equal to or smaller than the average speed of the object over the same
interval of time.
